Any eonvenii-ii, means are pri/vided to support undpi'o )el the til-read through the tubular or trf'mgrlr-lilie members g in the direetieii el and Drel'erirbly substantially com cent1-leali fritti their central longitudinal axes, suoli centrality being of importance iii assisting lille desired equality 0l' temperature on :dl sides el die tlm-mul. Such means are, .Vor example, in the present instance, dieseidtulmler member should lie much greaterv grauninetieelly indicated in Figs. l and 5, by y which the requisite electrical contacts may be effected. Saidears are conductors and are secured to conducting bars i, a, (see Fig. 7) each connected by a conductores a', y, with a source of electrical energy not shown, the required temperatures being attained by resistance ot the members when the current is turned on, the current passing from conductor x through fi, g anda to conductor y.

Where, as is desirable in practice, a considerable number of said members are heated by the current from a single source, 1t is preferable to install in parallel a group of several members q, Fig. 8, and install in series a number of said' groups as shown diagram matically in Fig. 8, the current being supplied t0 the extremes through a transformer as shown, which receives'the primary current at normal tension, and supplies it to the secondary coil at a tension and volume corresponding to the number and section ol all 'the members and to the required tempera ture. rlhis temperaturewvill depend upon the number of threads and the speed at which they are ropelled 4through said members. To regu ate it the number of turns enployed of one or both et' the primary, or secondary windings, may be varied by means of a contact stud switch as indicated in Fig'. 5%. With a suihcient number of contact-studs one may thus produce any required teinperature.

ln certain classes of threads a more )erect singeing is obtainable by passing tllieni successivelyT through several consecutive tubular or trough-like members'disposed in series as shown in Fig. il', er in parallel with return motion as shown" in Fig. 4. Where the latter method is employed., the plurality oitl tubular or trough-like members may advantageously be condtructed out of a unitary sheet of said metal, corrugated to roduce the required group of'parallel l'tubu ar pa. sages, each provided with an o ening eX- tendingcontinuously therethroug i in parallelisin with its central longitudinal axis, as shown inl Fig. 5. Where such sequences are employed the thread is alternately highly heated and intermediately subjected to oxidizing action in an atmosphere with particularly advantageous results.

Considering the minute internal diameter of said tubular or troughflike members, the close approximation of the thread to their interior suiiaces, and the high temperature of latter when heated, and the very considerable expansions and" contractions to which they are necessarily subjected under variations of temperature, it will be appieciated that a highly important condition t6 be maintained is that oi their constant rectitude and avoidance of buckling thereof. lt' both extremities of such members are ixedly supported prohibitory buckling is inevitable, with the result that the thread is injured or severed by burning through. lille have obviated these diliculties by the expedient oi' -:redly supporting one end only oi' said members and movably supporting the other end. @ne end being thus substantially free, their expansion 'and contraction are unimpeded and buckling of the said membersd prevented. ll the members are disposed? vertically, suspended at their upper ends from a stationary support, their own weight, plus that of the said movable supports at their lower 'ends will sulhce to maintain their rectilineality. Il preferred, or i they are horizontally disposed, this r tension may be effected by aid of ten nal springs, as, for example, p as shown in 7. ln this 'mstance the members g are connected by their ears 7L with a stationary supporting electrically conductive bar i, to

.which may be -l'urther secured lprote@ting trames 7C, the body oi the members ,y being free in the grooves m of the latter.

members y are by similar ears, at their opposite extremities, secured to the electrically conductive movable supporting bar 'a which is l'ree to rccipro late relatively to the frames /t' but without contacting therewith. Tensional springs p, p, bear against a to conlstantly press it in a direction outward or away from i. Therefore, as the members g' expand and lengthen under rise ot temperature they are positively pulled straight and as they cool they contract against the stress ol the springs p, and are thereby prevented from buckling.

To avoid undue radiation from the members g and undesirable drafts and laccess of Elo ai'r ol' relatively low temperature, Athus dis-l 'turbing the desired equality of ,temperature on all sides of the thread, the members may be covered, or inclosed by screens or shields t diagrammaticallly indicated in but not shown, for clearness ol' other parte, in Fig. 7. These inclosing screens or shields may be constructed of any desired. form or material consistently with their effective protection of the members and threads in the particulars mentioned. i Y

The delicacy and certainty ofoperation alici-ded b our said improvements is such. as to ena .le to be singed, or gassed thereby, materials hitherto incapable of `such treatment.
